The paper deals with the issue of negative phenomena related to the field of communication in the workplace and has the character of an interdisciplinary study using knowledge from the theory of law, personnel management, psychology, theory of communication and media studies. The main aim of the paper is to examine the issue of communication in the workplace with a specific emphasis on mobbing and cybermobbing as negative aspects and consequences of this communication, and the legislative and non-legislative options for protection against them. In the paper, we present a reflection of the basic theoretical background and defining frameworks from various author's perspectives. In this paper, we focus on the origin of mobbing, its forms, and manifestations, as well as a brief description of cyberspace as a determinant for the transformation of mobbing into the virtual environment. The dominant part is the second section of the paper, where the current possibilities of legislative protection in the context of victims of mobbing and cybermobbing are identified regarding various manifestations and selected types of aggressive communication and behaviour.
